Tiggywinkle, if you look back on this thread to earlier in the year, you will see a post made by the owner advising that she already runs a playgroup at the property not a nursery so apologies for misleading you and adding fuel to your fire of trying to do your hardest to pour trouble on this person and her attempts to grow her business. You clearly are so obsessed with this that you are trying to explore every avenue of wrecking her life. How do you know that they don't have fire retardent doors, or even if they need them. Certain regulations are only triggered by certain levels and types of activity.
I conclude that you are no more interested in child welfare than Freddy Kruger as if you were you would be more supportive of legitimate attempts to set up a much needed high quality facility for the children of Forest Hill.
